A dendrite conducts nerve impulses ________ the cell body.
- A. away from
- B. toward
- C. both toward and away from
- D. around, bypassing
Correct Answer: B
Rationale: Dendrites are specialized structures that receive nerve impulses from other neurons and conduct them toward the cell body. They are branched extensions that increase the surface area for receiving signals. The electrical signals generated by neurotransmitters binding to receptors on dendrites travel toward the cell body, where they are integrated to determine whether the neuron will fire an action potential. This directional flow is essential for neural communication.
